You can configure the HP MA and EMA systems to provide functions that are
compatible with the Storwize® V3500
system.
Before you begin
This task assumes that the system is not in use.
About this task
Note: When you configure the Storwize V3500
clustered system to work
with an HP MA or EMA, you must not exceed the limit of 96 process logins.
Complete these steps to enable support of an HP MA or EMA system.
Procedure
- Verify that the Storwize V3500 system is
clear of errors.
- Ensure that the HP StorageWorks Operator Control Panel
(OCP) on each system is clear of errors. The Operator Control Panel
consists of seven green LEDs at the rear of each HSG80 controller.
- Ensure that you can use an HP StorageWorks command-line
interface (CLI) to configure the HSG80 controllers.
- Issue the SHOW THIS and SHOW OTHER commands to verify
these items:
- Ensure that the system firmware is at a supported level. Refer to the following web site for
the latest firmware support:
www.ibm.com/support.
- Ensure that the controllers are configured for MULTIBUS FAILOVER with each other.
- Ensure that the controllers are running in SCSI-3 mode.
- Ensure that MIRRORED_CACHE is enabled.
- Ensure that the Host Connection Table is not locked.
- Issue the SHOW DEVICES FULL command to verify these items:
- Ensure that none of the LUNs are TRANSPORTABLE.
- Ensure that all LUNs are configured.; that is, the LUNs must report their serial numbers and
TRANSFER_RATE_REQUESTED correctly.
- Issue the SHOW FAILEDSET command to verify that there are no failing disks.
Note: To verify, no orange lights should be lit on any disks in the system .
- Issue the SHOW UNITS FULL command to verify these items:
- Ensure that all LUNs are set to RUN and NOWRITEPROTECT.
- Ensure that all LUNs are ONLINE to either THIS or OTHER controller.
- Ensure that all LUNs that are to be made available to the Storwize V3500 system have ALL access.
- Ensure that all LUNs do not specify Host Based Logging.
- Issue the SHOW CONNECTIONS FULL command to verify that you have enough spare
entries for all combinations of Storwize V3500
ports and HP MA or EMA ports.
- Connect up to four Fibre Channel cables
between the Fibre Channel switches
and the HP MA or EMA system.
- Ensure that the Fibre Channel switches are zoned so that the
Storwize V3500 system and the HP MA or EMA system
are in a zone.
- Issue the SHOW THIS command and SHOW OTHER command to
verify that each connected port is running. This example is similar to the output that is displayed:
PORT_1_TOPOLOGY=FABRIC.
- Issue the SHOW CONNECTIONS FULL command to verify that the new connections
were created for each Storwize V3500 port and HP
MA or EMA port combination.
- Verify that No rejected hosts is displayed
at the end of the SHOW CONNECTIONS output.
- Perform these steps from the Storwize V3500 command-line
interface (CLI):
- Issue the detectmdisk CLI command
to discover the storage system.
- Issue the lscontroller CLI command
to verify that the two serial numbers of each HSG80 controller in
the storage
system appear
under the ctrl_s/n (controller serial number) column
in the output. The serial numbers appear as a single concatenated
string.
- Issue the lsmdisk CLI command to
verify that the additional MDisks that correspond to the UNITS shown
in the HP MA or EMA system.
Results
You can now use the Storwize V3500 CLI
commands to create a storage pool. You can also create and map
volumes from these storage
pools. Check the front panel of the Storwize V3500 system to ensure that there are no
errors. After the host has reloaded the Fibre Channel driver, you
can perform I/O to the volumes. For more imformation, see
the host attachment information.
